{"product_id":"12-e0102-k","title":"HydroQuip 4.0kW Epoxycast Flo-Thru Heater Element (12-E0102-K)","description":"\u003cp\u003e\u003cstrong\u003eHydroQuip and Therm Products heater elements:\u003c\/strong\u003e Therm Products is a division of HydroQuip and supplies heating components for spa, hot tub, and hydrotherapy equipment. The line includes flow-through elements, titanium versions, epoxy-encapsulated configurations, and specialty flange and coil designs for servicing compatible heater assemblies. A replacement heating element is chosen by its actual electrical and mechanical specification—not by the brand of the spa alone. Before ordering, compare the original heater part number, power rating, voltage, element shape, mounting hardware, housing dimensions, and terminal arrangement with the replacement. That careful comparison helps avoid ordering an element that looks similar but cannot be installed or operated correctly.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eHydroQuip 4.0kW Epoxycast Flo-Thru Heater Element (12-E0102-K)\u003c\/strong\u003e is a 4.0kW replacement component in the \u003cstrong\u003e10-inch epoxycast flow-through\u003c\/strong\u003e family. The selected power rating represents a 4.0kW heating rating; matching the control system and the original circuit is essential even when another element shares its physical length. Epoxycast identifies a specific encapsulated element design within the flow-through family. Confirm that the original heater uses this construction and compare the mounting interface and available housing clearance; an ordinary flow-through item should not be assumed to substitute automatically. Its manufacturer reference is \u003cstrong\u003e12-E0102-K\u003c\/strong\u003e, which is the most reliable identifier when comparing the listing to service paperwork, a parts diagram, or the original heater assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMaterial and electrical match:\u003c\/strong\u003e The supplier identifies Incoloy as the element material for this configuration. The alloy designation helps distinguish it from titanium versions that may share a similar power rating but have separate manufacturer part numbers. The structured supplier specification lists \u003cstrong\u003e230V\u003c\/strong\u003e, but the supplier headline also references 240V; verify the exact required voltage from the original element and current manufacturer documentation before publication or installation. Heating element replacement involves both the electrical system and a water-containing heater housing. The correct part must be installed with sound seals, suitable water-flow protection, and the mounting hardware required by the original equipment manufacturer. Do not select an element solely because its nominal output matches another product in the HydroQuip catalog.\u003c\/p\u003e\u003ch3\u003eKey Features and Replacement Considerations\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower-rating match:\u003c\/strong\u003e This part is identified as 4.0kW; a 4.0kW heating rating; matching the control system and the original circuit is essential even when another element shares its physical length.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement form and fit:\u003c\/strong\u003e Epoxycast construction with 10-inch flow-through format.
